In a hypothetical population of 1000 snapping turtles, there exists a gene with two alleles: D & d. You find that 440 of the turtles are homozygous dominant (DD), and 210 are homozygous recessive (dd). What is the frequency of the heterozygote (Dd) in the population? Group of answer choices A) 0.17 B) 0.26 C) 0.35 D) 0.50 E) 0.70

Answer #1

# total turtles = 1000

# DD = 440

# dd = 210

# Dd = 1000 - (440 + 210) = 350

Genotypic frequency of Dd = 350/1000 = 0.35

Answer is Option C.
